On top of that, it could be arranged so that cloud-maintainers had almost no knowledge whatsoever of what cloud-users were doing. Cloud-maintainers could abstain entirely from using their own cloud (maintaining a separate one for their own use). This would mean that LEOs who infiltrate the cloud-maintainer organization would not gain any information on cloud-user activities, and LEO that infiltrated a cloud-user organization wouldn't gain any ability to compromise the network.
Implemented this way, such an infrastructure would be a different order of difficulty entirely to penetrate. In contrast, Donnie Brasco as a lone agent could gain access to both operational activities and organizational structure of the Cosa Nostra. In this scheme, he would have to choose one or the other. Also, two LEOs attacking the infrastructure from both sides would have to collude to make sure their intelligence would overlap, and this would make their activity detectable.
